OIL-PRESS MAT.

SPECIFICATION forming part of Letters Patent No. 611,316, dated September 2'7, 1898.

Application filed January 19,1898. Serial No. 667,111. (No mode.)

To all whom it may concern.-

Be it known that I, WILLIAM F. HANSE, a resident of the city of New York, (Brooklyn,) in the county of Kings and State of New York, have invented certain new and useful Improvements in Oil-Press Mats, of which the following is a specification.

My invention relates to the production of an efficient oil-press mat.

In pressing oil from seeds it is customary to employ a series of mats upon which the seeds are placed and the whole compressed in a press, which squeezes the oil out from the seeds, the oil which remains in the mat being extractedafterward. Ithasbeenfound,however, that these mats rapidly'wear away at their middle portions, owing to the fact that the greatest strain is brought to bear at that portion of the mat. Various schemes have been devised to obviate the bad effects of these strains, which, as will be well understood, rapidly destroyed the mat. None of these devices have been successful. For instance, it has been proposed to employ metallic wires laid alongside the warp-threads of the mat, but it has been found'that these wires not only cut the warp-threads, but, having little elasticity, break and produce rapid warp-threads at the middle portion of the fabric are crowded together more than at the edges of the fabric and are in greater num- Fig. 2.

bers at the middle than at the edges, as shown.

I prefer to gradually decrease the number of warp-threads per inch from the center to the edges of the fabric in any desired proportion. The fabric is preferably made of camels hair, as I have found that camels hair, among other qualities, strips easier than other materials heretofore employed.

What I claim, and desire to secure by Letters Patent, is-

1. As a new and useful article of manufacture, the herein-described oil-press mat havby the fabric is strengthened at the point where the greatest strain is applied.

2. As a new and usefularticle of manufacture, the herein-described oil-press mat, comprising warp-threads and weft-threads, the

warp-threads at the middle of the mat being in greater numbers per inch than at the edges of the mat, and gradually decreasing in numbers per inch from the middle of the mat toward the edges, substantially as described and for the purposes set forth.

3. An oil-press mat comprising a twill fabric composed of camels-hairthreads, the warpthreads of the fabric being in greater number per inch at the middle portion of the fabric than at the edges.

4. An oil-press mat comprising a twill fabric composed of camels-hair threads,the warpthreads of the fabric being most numerous at the middle of the fabric and decreasing in numbers per inch gradually on both sides of the middle of the mat, substantially as described.
